Midpoint
Figure 3: Midpoint indicator results for categories that contribute to Ecosystem Quality endpoint impact metric, using a functional unit of 1 kg pesticide. Data for different midpoint indicators are measured according to different units, but here they have been normalized by normalized the life cycle impact value of Imidacloprid (“I” columns) to a value of 1.0. Thiamethoxam (“T” columns) values for each midpoint category were normalized according to the Imidacloprid scale, to illustrate the comparison between the two pesticides. In all columns, light colored bars represent impacts for the Production stage and dark colored bars represent impacts from the Application stage. The Transportation stage is too small to be observable in all categories.
